From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Chichi's Mother's only appearance is in a painting of her sitting in Gyumao's hands holding Chichi as an infant in "Dress in Flames". In the painting, her face is not shown since it is blocked by decorations, but she has the same hair as Chichi and dresses the same way Chichi does when she gets older. She wears a turquoise cheongsam with purple pants underneath and pink socks and shoes. According to the painting, she is almost as as big as the Ox-King's hand.
